We are building a portfolio of agentic operations — production-grade AI agents that plan, act, and continuously improve the everyday experiences of our employees. The mission is to eliminate friction from the moments that matter employees spend more time on work that matters and less time on tickets, forms, and queues.

As Senior Lead Software Engineer, AI Engineering, you will be a hands-on senior individual contributor on this team, reporting to the Executive Director who owns the agentic platform and flagship agents. You will be the technical anchor of one or more agent squads: designing the agent, writing the code, running the evaluation harness, integrating with enterprise tools (ServiceNow, Databricks, identity, endpoint), and taking the pager when it ships.

You will pair with engineers, review PRs, drive design docs, mentor the squad, and be personally accountable for the correctness, safety, cost, and business impact of the agents you build.

Job responsibilities

Design and build agents
- Own the end-to-end design of production agents: planner, tools, memory,



retrieval (RAG / GraphRAG), guardrails, human-in-the-loop, evaluators.
- Implement using the team's Model Context Protocol (MCP) stack — write MCP servers/clients, define tool schemas, negotiate capabilities, and integrate securely with enterprise systems.
- Choose the right orchestration pattern (single-agent, planner-executor, supervisor-worker, debate/critique) for each use case; reject unnecessary complexity.

Evaluation, safety, and quality
- Build and maintain the evaluation harness for your agents: gold sets, offline benchmarks, LLM-as-judge with human calibration, online A/B, regression gates in CI/CD.
- Instrument every agent with business KPIs (deflection rate, time-to-resolve, CSAT, cost per interaction) and quality KPIs (task success, groundedness, refusal correctness, safety incidents).
- Partner with cyber, privacy, and model risk to make guardrails concrete: PII handling, prompt-injecti
